    Abstract:
    The analyzing power Ay(θ) for neutron elastic scattering from C12 has been measured for 33 neutron energies between En=2.2 and 8.5 MeV in the angular range from 25° to 145° in the laboratory system. The primary motivation for these measurements is the need for an accurate knowledge of Ay(θ) for C12(n,n)C12 elastic scattering to enable corrections to high-precision neutron-proton and neutron-deuteron Ay(θ) data in the neutron-energy range below En=30 MeV. In their own right, C12(n,n)C12 Ay(θ) data are of crucial importance for improving both the parametrization of n-C12 scattering and our knowledge of the level scheme of C13. The present Ay(θ) data are compared with published data and previous phase-shift-analysis results. © 2005 The American Physical Society.
